TAKE-UP MECHANISM FOR LOOIVIS- I A To all whom it may concern.-

Be it known thatI, OTTO W. SoHAUM, acitizen of the United States, residing in Philadelphia, Philadelphia county, Pennsylvania, have invented certain new and useful Improvements in Take-Up Mechanisms for Looms; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, and to characters of reference marked thereon, which form a part of this specification.

This invention relates to take-u p mechanisms for looms, and particularly to take-up mechanisms for narrow-ware looms, where the several sand-rollers are commonly arranged on and driven by a single shaft.

My invention has for its object to provide a take-up mechanism for looms in which the sand-roller will be so connected with the shaft on which it is mounted that while the motion of the shaft will in the normal operation be transmitted to the roller positively and without slipping the weaver can adjust the roller on the shaft, as in picking back, with a facility, convenience, and accuracy that will produce a considerable saving of time and labor and an enhancement of the quality of the goods woven over take-up mechanisms now in use.

My invention will be found fully illustrated in the accompanying drawings, wherein- Figure 1 is a verticalsectional view of the front portion of a narrow-ware loom provided with my improved take-up mechanism.

Fig. 2 is a view of one side of the sand-roller. Fig. 3 is a sectional view of the sand-roller on the line a: a: in Fig. 2. Fig. 4: is a view of the other side of said sand-roller, and Fig. 5 is a view of a certain wrench.

a in the drawings is a loom-frame; Z), thebreast-beam; 0, a roller or glass bar over which the finished goods extend at the breastbeam;- d, a bracket carrying the part 0; e, the sand-roller over which the goods next pass, the same being mounted on the usual suitablydriven shaft f,- g, a presser-roller over which the goods next pass, the same having its trunnions h bearing against vertical faces on the bracket (Z, and i the cloth-beam, which is held up against the sand-roller by the usual spring-pressed bracket 1', which carries it.

The sand-roller is constructed as follows: is is its perimeter or rim portion, faced, as usual, with sandpaper Z or the like, on its hub, and 02 its web. The web is set somewhat to Specification of Letters Patent. Application filed January 28 1905. Serial No. 243,046.

one side of the middle plane of the roller, so that it is readily accessible to a certain wrench hereinafter described for a purpose to be set forth. The hub m is provided with a split 0 and for a part of its circumference is detached from the web a, which may be effected by providing a curved opening 19 in the web about the hub. In order to reinforce the whole structure, ribs 9 and r are provided at both sides of the split 0 and on the right-hand side of the web a, as'seen in Fig. 3, the one, q, being integral with the perimeter, the web, and the hub, and the other, r, integral with the perimeter and the web and extending approximately to the opening 19. The hub is in the form of a cylinder whose length approximates the width of the perimeter of the roller, so that thus it has a broad contact with the shaft f when properly clamped thereon, as hereinafter described. Rib r and the opposite portion of the hub q are provided with checks 8 and 2,, respectively. Between these cheeks extends a bolt it, having a head 4) formed as acone or wedge and a nut w, screwed thereon and also formed as a cone or wedge. The cheeks may be rabbeted out, as at w, to receive the nut w, so that in screwing the bolt a into the nut the nut will be prevented from turning. By screwing up the bolt and nut, arranged as they are best shown in Fig. 3, the hub will be clamped more or less tightly on shaft f. In order to prevent sidewise movement of the bolt and nut, the cheek portions may be recessed, as at w, to receive the nut and the head of the bolt. By this arrangement the sand-roller may be made to have a grip on the shaftf which will be sufficient to insure its turning with the shaft not-,

withstandingthe back pull of the let-off mechanism of the loom and yet permit of ready and accurate adjustment upon the application of sufficient power to turn the roller on the shaft when such is necessary, as in picking back.

In Fig. 5 I show an implement for turning the roller on the shaft. This is a shank or lever y, having one end flattened, as at .2, and provided on each side with a pair of lugs 1, the two pairs of lugs being set obliquely to the longitudinal axis of the shaft. The implement thus forms a spanner, whose lugs 1 may be engaged in holes 2, formed in the web a of the roller, which latter being disposed at one side of the middle plane of the roller is thus readily accessible to be engaged by the spanner. On account of the oblique arrangement of the lugs either the one or the other thereof can be engaged with the roller Whatever happens to be the position of the latter relatively to other parts. The implement y is formed at its other end with a squared socket 3, making thereof a Wrench, whereby thebolt Q; can be manipulated.

Having thus fully described my invention, what I claim, and desire to secure by Letters I Patent, is

The combination of a shaft, a roller ar ranged thereon and havingasplit or break in its hub portion interrupting the continuity thereof, said hub portion being otherwise I5 continuous or unbroken and said roller also having an opening extending around the hub from said split or break to at least as far as a point diametrically opposite the split or break, and means, arranged in said opening between the hub portion and the outlying Z0 portion of said roller and adjacent said split or break, for clamping said hub portion to the shaft, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of 5 January, 1905.
